...lity issues
- Replace gradle commands with ./gradlew to use project-specific Gradle version
- Fix compatibility issues with Gradle 9.x in GitHub Actions
- Use -b option with gradle wrapper (Gradle 8.14.3) which still supports it
- Update both tests.yml and codeql-analysis.yml workflows

...rror
- Change bootstrap step from './gradlew -b bootstrap.gradle' to 'gradle -b bootstrap.gradle'
- Bootstrap step now uses system gradle to download the wrapper
- Build step continues to use './gradlew' after bootstrap creates it
- Fixes 'No such file or directory' error in GitHub Actions

- Fix run command indentation in tests.yml and codeql-analysis.yml
- Ensure proper YAML syntax for GitHub Actions
- Commands should be directly under 'run:' not indented further

... 9.x compatibility issues
- Add chmod +x ./gradlew to ensure wrapper is executable
- Use ./gradlew -b bootstrap.gradle instead of gradle -b bootstrap.gradle
- This avoids system Gradle 9.1.0 which removed -b option
- Use project's Gradle wrapper (8.14.3) which supports -b option
- Should resolve 'Unknown command-line option -b' errors

- Update gradle-wrapper.properties to use Gradle 9.1.0
- Replace deprecated -b option with -p option in workflows
- Update workflow files to use ./gradlew -p . bootstrap.gradle
- Update documentation to reflect Gradle 9.x requirements
- Modernize build system for future compatibility
- Addresses DATAFU-183: GitHub Actions CI failing with Gradle 9.x

- Keep Gradle 8.14.3 wrapper (compatible with existing codebase)
- Use ./gradlew -b bootstrap.gradle (works with Gradle 8.14.3)
- Add chmod +x ./gradlew to ensure wrapper is executable
- This avoids system Gradle 9.x compatibility issues
- Addresses DATAFU-183: GitHub Actions CI failing with Gradle 9.x
Note: Gradle 9.x upgrade requires significant buildSrc plugin updates
due to breaking changes in JavaExec and other APIs.
